LOOSE-LEAF BINDER.

Patented June 28, 1910.

Application filed August 19, 19 09. Serial No. 513,560.

To all whom 'it may concern:

Be it known that I, WILFRED C. TRAHER, a subject of the King of GreatBritain, and a resident of London, in the Province of Ontario, Canada,have invented a new and Improved Loose-Leaf Binder, of which thefollowing is a full, clear, and exact description.

This invention relates to loose leaf binders, and more particularly to adevice of this class comprising a member adapted to be secured in anysuitable manner to a cover, a slide having a guiding relation with themember, and leaf holders movably held by the member, the slide beingformed to secure the holder against movement in one position of theslide, and permitting the holder to be opened for the insertion orremoval of leaves when the slide is in a second position.

The object of the invention is to provide a simple, strong and durableloose leaf binder which can be inexpensively manufactured,

which comprises few parts, which can be easily attached to and detachedfrom covers of diiferent kinds, by an unskilled person, and by means ofwhich the leaves can be securely held against displacement permittingthem to be turned easily.

The invention consists in the construction and combination of parts tobe more fully described hereinafter and particularly set forth in theclaims.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views, and in which Figure l is aperspective view f an embodiment of my invention showing the sameapplied to a cover; Fig. 2 is aplai view of the device; F ig. 3 is aninverted plan view of the binder; Fig. 4.- isa transverse section on theline 44 of Fig. 2; Fig. 5 is a view similar to Fig. 4 showing the leafholder in a different position; Fig. 6 is a perspective view of part ofthe slide; Fig. 7 is a similar view of part of the retaining plate ormember; and Fig. 8 is a similar view of the leaf holder showing partbroken away.

Before proceeding to a more detailed explanation of my invention itshould be clearly understood that while I prefer to fashion certain ofthe parts of the same from stamped or otherwise formed sheet metal, anyother material adapted for the purpose can be employed. The leaf holdersare preferably formed from wire bent though into shape, as will appearmore clearly here mafter. I have illustrated the device as -attached toa cover by means of rivets, but I do not wish to limit myself to thesedevices for aflixing the retaining plate in place. The binder of myinvention can be so attached to and detached from a cover that anunskilled person, such as a school child, will have no difficulty inremoving the device from one cover and placing it upon another, wherebythe life and usefulness of the binder are increased.

Referring more particularly to the drawings, I provide a retaining plateor member 10 preferably fashioned from metal, and having the oppositelongitudinal edges formed into arched flanges 11. The member hasopenings 12 theret-hrough adapted to receive rivets 13 or the like forsecuring it in place upon the back A of a cover, which comprises inaddition, the usual cover sides B, as shown most clearly in Fig. 1. Thearched flanges 11 extend beyond the body of the retaining plate 10 sothat this is offset from the back Ato permit the slide 14 to move freelyunder the member 10.

The slide has an arched flange l5 guidingly engaging one of the flanges11, and a curved flange 16 guidingly engaging the other flange 11 of themember 10. The flanges 15 and 16 are located at the oppositelongitudinal edges of the slide. At one end the slide has an upwardlydisposed extension 17 by'means of which it can be easily manipulated. Ithas, further, aslot 18 which receives one of the rivets 13, the ends ofthe slot limiting the movement of the slide.

I provide a leaf holder comprising an elongated body portion 19, and atthe extremities thereof, laterally disposed curved parts or rings 20,the ends of which are spaced from the body portion 19 and whlch serve tohold the loose leaves C, the latter being provided with the usual holesD for the purpose. The part 19 constitutes the pivot and is received,under one of the arched flanges 11, the latter haying cutaway parts 21to permit the pro ect1on of the parts 20 of the holder, as 1s shown mostclearly in Fig. 2. The opposite flange 11 has cutaway parts 22 toreceive the free ends of the parts 20 of the holder. The flange 15 ofthe slide has cutaway parts 23 whlch are so arranged that the slide canmove freely without interference on the part of the holder. The flange16 of the slide has cutaway parts 24 which in a predetermined positionof the slide are adapted to register with the cutaway parts 22 so thatthe holder can be pivoted about the part 19, and to permit the insertionand removal of the free ends of the parts 20 of the holder. It willbe"understood that.when the holder is so positioned the free ends of theparts 20 are within the cutaway parts 22 of the flange 11, that theslide can then be so arranged that the cutaway parts 24 do not registerwith the parts 22, and consequently it is impossible to retract theholder, and the latter will be held in a closed position. When the slideis adjusted so that the parts 24 register with-the cutaway parts 22, theholder can be swung about the pivot part 19 to release the ends of theparts 20 for the insertion or removal of leaves 0. The curved form ofthe parts 20 of the holder may be of any suitable kind provided theextremities are so formed that the flange 16 is operative to hold themagainst removal when the slide is in a predetermined position such thatthe cutaway parts 24 do not register with the cutaway parts 22.

Preferably, the slide 14 is so proportioned that but one slot 18 isnecessary, as is shown most clearly in Fig. 3.: Furthermore, but onecutaway part 24 need be provided as in one position of the slide itclears the one cutaway part 11.

Having thus described my invention, I claim as new, and desire to secureby Letters Patent 1. A loose leaf binder, comprising a member adapted tohave a fixed attachment with a cover and offset therefrom, a slide undersaid member, and a pivoted leaf holder carried by said member, saidslide being formed to secure said leaf holder against movement in apredetermined position of said slide.
